IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 215,508, dated May 20,1879 application filed October 22, 1878.

To all whom it may concern.-

Be it known that I, JAMES H. OovEL, of

v the city and State of New York, have invented an Improvement inOar-Axle Boxes, of which the following; is a specification.

I make use of an oil-vessel that is separate from the axle-boxand ispressed toward the axle by a spring or springs beneath the same. Thisbox has side wiping-pads, that serve to remove surplus oil, and also toclean the jour- 11211 from dust and dirt. The surplus oil is returned tothe oil-vessel. There is also a lubricating-pad within a case that isprovided with springs, to raise up said case and keep it in contact withthe journal. Oil that usually would run along the shaft and pass to thewheel is scraped ofl' and returned to the oilvessel.

In the drawings, Figure 1 is a longitudinal section of the improvedaxle-box. Fig. 2 is a cross-section of the same, and Fig. 3 is a plan al of the oil-vessel detached.

The journal a, bearing 1), and axle-box o are of any usual construction;but the box is adapted to receive within it the oil-vessel d, that hasbeneath it one or more springs, e, that tend to lift the same.

The sides'of the oil-vessel are extended up at f, and provided with aninner casing, g, between which parts f and g there is a wiper, h. Thereis one of these wipers at each side above the oil-vessel; hence as theoil-vessel is raised by its springs the wipers come into contact withthe journal and remove surplus oil or dust, and the oil that mayaccumulate in or upon these wipers passes down and runs from the bottomof the wipers back into the oil-vessel d. This oil-vessel is open at itsupper surface, and receives into it the case l, that is in the form ofan oblong tube, containing the section of thick felt m, or othersuitable material, that will act to convey oil up to the under side ofthe journal.

At the sides of this case l, near the upper edges, there are flanges a,occupying recesses 'sprin gs 0 beneath the said flanges n, that serve toraise the case 1, and with it the pad 'm. so

.as to maintain contact between the same and the journal.

Spring-scrapers r, at each side of the inner or back part of thejournal, press against such journal and scrape the oil off, and preventthe same passing to the dust-plates or out upon the wheel. The ends ofthese spring-scrapers should be inclined or wedge-shaped, so as to forcethe oil toward the wipers h, and return the same to the oil-vessel.

Fibrous material may be inserted between the oil-vessel and the insideof the axle-box, to prevent the box being displaced by the mo tion ofthe truck and frame.

I claim as my invention- 1. The combination, in a car-axle box, of aseparate oil-vessel, d, springs c, oblong ease I, provided with flangesn, and the felt wick m, substantially as and for the purposes set forth.

2. The separate oil-vessel d, within the axlebox, in combination withthe casings f 9, extending upward from said oil-vessel d, and the wipersh ateach side of the journal and between the said casings f g,substantially as and for the purposes set forth.

3. The lubricating-pad m and its case l, in combination with theseparate oil-vessel d and the springs o, to raise the lubricating-pad,substantially as set forth.

4. The combination, with the axle and box, of spring-scrapers applied atthe inner end of the journal and the oil-vessel with which they areconnected, substantially as specified.

Signed by me this 12th day of October, A. D. 1878.
